I mainly program Android apps, many for my side business.
Some people here have said "mobile has peaked". I go around with my Android mobile phone, and I have trouble finding out what time stores close. I have trouble finding nearby supermarkets. I certainly can't find out if supermarkets have an item in stock, or if the item on sale. I can't find a nearby bathroom to use.
We are nowhere near mobile peaking. Yes, there may be a little bubble now that fizzles out before it comes back again. Kind of like how there was a website bubble, which fizzled in 2000, and then four years later Facebook was started. The day I can punch into my phone asking where I can buy a chair, and get back most of the local stores, and what they have in stock, and for what price - that is when the "smartphone bubble" is soon to "burst".
And on that note, the more places mobile puts it's fingers, ultimately, the more places that someone needs to make sure the finger points to the right thing. Every google maps, yelp review, craigslist post, etc., needs someone ultimately to vet it's place in reality before said reality can be made useless by it. I think we're on the cusp of mobile overload, where we're going to see more and more specialized mobile services made useless because we simply don't have the manpower to wire them up well without taking that manpower from something else.
So, while we may not be peaked in terms of what could be done, we're nearing the point where what WILL be done is starting to look more and more focused on the things that grab quick money.
Oddly, I think the next big revolution will be the generation that's tired of being chained to their devices and subscriptions and services, and starts to devolve back to actual interpersonal relationships. I'm seeing it every day with those of us who grew up without it, had it, and realized that it's not quite the silver bullet for living it marketed itself as.
Siri still sucks, Google maps still gets you lost, and visual studio still blows on a touchscreen laptop.
These new functionalities you speak of in the future like finding what items are in stock nearby are all more of an information gathering exercise rather that technological. We could do all that you talk about now but it would require a massive unified collaboration with shop owners for example to adhere so a common data interchange standard.
I think the challenges are of a more political nature than technological.
